Nope. I don't have any of my T7 left, which would make Lifebloom more beneficial.
I now have a full set of T8, which make Rejuvenation and Swiftmend super-ubar.
* 2 pieces: Increases the healing done by your Swiftmend spell by 10%.
* 4 pieces: Your Rejuvenation spell also provides an instant heal for your target.
End of story - Do what works best for you. If you end the fight with a bit of mana, and no one dies due to lack of heals, you are doing your job. lol
